Conductance noise in nano-patterned PbS quantum dot arrays
Tamar S. Mentzel, Nirat Ray, Neal E. Staley +3
We report unexpectedly large noise in the current from nanopatterned PbS quantum dot films. The noise is proportional to the current when the latter is varied by changing the sourc…
Electric-field driven insulating to conducting transition in a mesoscopic quantum dot lattice
Neal E. Staley, Nirat Ray, Marc A. Kastner +2
We investigate electron transport through a finite two dimensional mesoscopic periodic potential, consisting of an array of lateral quantum dots with electron density controlled by…
Multiferroic Properties of Nanocrystalline BaTiO3
R. V. K. Mangalam, Nirat Ray, Umesh V. Waghmare +2
Some of the Multiferroics [1] form a rare class of materials that exhibit magnetoelectric coupling arising from the coexistence of ferromagnetism and ferroelectricity, with potenti…
Coupling between magnetic ordering and structural instabilities in perovskite biferroics: A first-principles study
Nirat Ray, Umesh V. Waghmare
We use first-principles density functional theory-based calculations to investigate structural instabilities in the high symmetry cubic perovskite structure of rare-earth (R La…
